我的问题有点神秘。如果我使用 PHPmyadmin 尝试，sql 代码的输出可以工作，但它不适用于 laravel。
这是查询生成器代码
$product= Product::leftJoin('ProductTransaction as PT',function($query){
$query->on('PT.ProductId','=','Product.id');
$todaysDate=Carbon::today()->toDateString();
$query->Where(DB::raw("date(`PT`.`CreatedAt`)=$todaysDate"));
})->Where(function($query) use($RetailerIds){
if (count($RetailerIds)) {
$query->WhereIn('RetailerId',$RetailerIds);
}
})->Where(function($query)use($Genders){
if (count($Genders)) {
$query->WhereIn('Gender',$Genders);
}
})->WhereHas("Stocks",function($query) use($Color){
if ($Color!='') {
$query->WhereHas('Color',function($query) use($Color){
$query->Where('Color','like',"%$Color%");
});
}
})->Where(function($query) use ($q){
if ($q!='') {
$query->Where('ProductTitle','like','%'.$q.'%');
$query->orWhere('Description','like','%'.$q.'%');
}
})->WhereHas('Stocks',function($query) {
$query->Where('Stock','!=',-1);
$query->WhereDate('CreatedAt','=',Carbon::today()->toDateString());
})->WhereHas('ProductTransactions',function($query) use($MinDiscountPrice,$MaxDiscountPrice,$todaysMaxDiscountPrice,$todaysMinDiscountPrice){
$query->WhereDate('Product.CreatedAt','=',Carbon::today()->toDateString());
if ($todaysMinDiscountPrice!=$MinDiscountPrice) {
$query->Where('DiscountPrice','>=',$MinDiscountPrice);
}
if ($todaysMaxDiscountPrice!=$MaxDiscountPrice) {
$query->Where('DiscountPrice','<=',$MaxDiscountPrice);
}
})->With(['ProductTransactions','ProductImages','ProductCategory','Retailer','Stocks.Size'])->OrderBy($orderBy)->paginate(15);
这是此查询填充的错误代码:
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '? where (select count(*) from `Stock` where `Stock`.`ProductId` = `Product`.`id`' at line 1 (SQL: select count(*) as aggregate from `Product` left join `ProductTransaction` as `PT` on `PT`.`ProductId` = `Product`.`id` and date(`PT`.`CreatedAt`)=2016-07-11 where (select count(*) from `Stock` where `Stock`.`ProductId` = `Product`.`id`) >= 1 and (`ProductTitle` like %test% or `Description` like %test%) and (select count(*) from `Stock` where `Stock`.`ProductId` = `Product`.`id` and `Stock` != -1 and date(`CreatedAt`) = 2016-07-11) >= 1 and (select count(*) from `ProductTransaction` where `ProductTransaction`.`ProductId` = `Product`.`id` and date(`Product`.`CreatedAt`) = 2016-07-11) >= 1)
但最有趣的一点是，如果我将 SQL 代码复制并粘贴到错误文本中，它就会起作用。这是我将其粘贴到 PHPMyadmin 的 SQL 代码
SELECT
count(*) AS AGGREGATE
FROM
`Product`
LEFT JOIN `ProductTransaction` AS `PT` ON `PT`.`ProductId` = `Product`.`id`
AND date(`PT`.`CreatedAt`) = 2016 - 07 - 11
WHERE
(
SELECT
count(*)
FROM
`Stock`
WHERE
`Stock`.`ProductId` = `Product`.`id`
) >= 1
AND (
`ProductTitle` LIKE % test %
OR `Description` LIKE % test %
)
AND (
SELECT
count(*)
FROM
`Stock`
WHERE
`Stock`.`ProductId` = `Product`.`id`
AND `Stock` != - 1
AND date(`CreatedAt`) = 2016 - 07 - 11
) >= 1
AND (
SELECT
count(*)
FROM
`ProductTransaction`
WHERE
`ProductTransaction`.`ProductId` = `Product`.`id`
AND date(`Product`.`CreatedAt`) = 2016 - 07 - 11
) >= 1
)
最佳答案
需要引用您的日期。将其作为变量传递，或引用它:
$query->Where(DB::raw("date(`PT`.`CreatedAt`)='$todaysDate'"));
或者
$query->Where(DB::raw("date(`PT`.`CreatedAt`)=?",[$todaysDate])); // Preferable, so that the database can handle it
